Cleaning
Clean the tips each time you clean the feeder (every 3-4) days using warm soapy water and sanitizing with 50/50 solution of white vinegar and water. Rinse thoroughly.

General Information
Your new set of Nectar Guard Tips virtually eliminates insect contamination from flying insects and many crawling insects. Allow a few days for your hummers to grow accustomed to your new feeder. Then, but only if insects are a problem, install the Nectar Guard Tips. Push the tips onto the Flower Port Stems that extend into the dish of the feeder. Avoid exposing the flowers and tips to high temperatures. Take care when washing the tips to avoid tearing them. Replace them every year or sooner if necessary.

Whether the species of birds you desire are native to your area, or migrating through, you can increase your chances of attracting them for a short or extended stay by providing the right feed, in the right feeder, installed in the right place.
